Flare Workshop - Introduction to TEEs on Flare I Nik Erzetic

Sat, May 2, 2026, 12:00 AM

In this workshop, Nik Erzetic, a developer at Flare Network, introduces Flare Smart Accounts and Flare Confidential Compute, two key pieces of Flare's infrastructure. Flare Smart Accounts use account abstraction to allow XRPL users to perform actions on the Flare blockchain without holding any Flare tokens, by bridging encoded instructions from XRPL payment transactions to personal account smart contracts on Flare. The session focuses primarily on Flare Confidential Compute, which leverages Trusted Execution Environments (TEEs) to extend blockchain security to handle private data and computationally heavy tasks. Nik walks through the architecture of TEE extensions on Flare, explaining how developers only need to modify two components — the instruction sender smart contract and the TEE extension code itself. He demos the FC Sign repository as a practical example, covering op types, op commands, and how the TEE securely handles private keys and transaction signing. The workshop concludes with notes on local development tooling for the hackathon and a brief Q&A. 00:00 Introduction 00:25 What Are Flare Smart Accounts 04:02 Account Abstraction and XRPL Integration 06:06 Encoding Custom Instructions 07:00 What Are Trusted Execution Environments (TEEs) 08:18 Flare Confidential Compute Architecture 09:38 Developer Workflow: Smart Contract and TEE Extension 10:36 TEE Proxy and Firewall Security Model 11:06 FC Sign Repository Walkthrough 12:48 Instruction Sender Smart Contract 14:04 Op Types, Op Commands, and Message Encoding 15:52 Go TEE Extension: Handlers and Config 17:32 Local Development Setup for the Hackathon 18:35 AI Skills for Building TEE Extensions 19:07 Q&A _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ *ETHGlobal Cannes 2026* This workshop is specifically for ETHGlobal Cannes 2026, a 3-day hackathon held April 3-5 at the Palace of Festivals and Congresses of Cannes, bringing together the most skilled web3 developers, designers and product builders from all around the globe for a weekend-long adventure to advance the Ethereum ecosystem!
